A company has two Internet links from different ISPs. They want to use both links for outbound traffic to improve resilience and utilization. They have configured two equal-cost default routes and applied a load-balancing policy. What is the primary benefit they will achieve?

Increased bandwidth for a single TCP session

Improved utilization of both links and redundancy

Simplified routing configuration

Guaranteed packet ordering for all traffic

You have configured per-flow load balancing across two equal-cost paths. You want to verify that the hash algorithm is distributing flows as expected. Which approach would give you the most useful information?

Use 'show route extensive' to see the hash algorithm

Monitor interface counters on both paths over a period of time

Use 'show pfe statistics' to see per-flow counters

Check the routing table for multiple next-hops

What is a typical use case for per-packet load balancing in Junos?

When the goal is to maximize link utilization and the traffic is tolerant of packet reordering

When the network carries many short-lived flows that are sensitive to reordering

When traffic consists of large, long-lived flows that need consistent latency

When all traffic must traverse the same path for security inspection

How does per-flow load balancing ensure packet ordering in Junos?

By sending packets in round-robin order across paths

By sending all packets of a flow over the same path

By buffering packets until all paths are synchronized

By using sequence numbers in the IP header

What is a key characteristic of per-flow load balancing in Junos?

It uses a hash of packet headers to select a path for each flow

It selects a path based on the current queue depth of each interface

It is only supported on MX series routers

It requires all flows to have the same source and destination
